Information on Verseon

Verseon was founded in 2002, and its proprietary drug discovery platform, developed entirely in-house, is the product of over ten years of research and development. The Company’s platform is a systematic, computationally-driven solution to achieve the molecular modelling accuracy necessary for rapid and cost-effective drug discovery. The platform designs hundreds of millions of novel, drug-like, synthesisable molecules for each drug programme and selects the most promising candidates for synthesis and laboratory testing. The Company generates multiple, chemically-diverse drug candidates for each discovery programme and, as such, is not reliant on the success or failure of a single drug candidate in the clinic.

Verseon’s platform is applicable to virtually any disease indication with known target protein structure. Current drug programmes feature:

First-in-class oral anticoagulants for various cardiovascular indications that have demonstrated successful proof of concept in preclinical efficacy studies and also substantially reduced risk of major bleeding relative to existing anticoagulants.

Potent kallikrein inhibitors that possess sufficient corneal permeability and other chemical properties for administration as a potential eye-drop treatment of diabetic macular oedema.

Novel angiogenesis inhibitors with low cytotoxicity that represent a new class of potential anti-cancer therapy.

Verseon is continuing to build a portfolio of discovery programmes, run in parallel, each with multiple drug candidates, as part of a rapid, cost-effective, scalable drug discovery process.

Terms used in this announcement have the same meaning as those used in the Company’s Admission Document. Copies of the Company’s Admission Document (dated 1 May 2015) are available on the Verseon website: www.verseon.com.

Background information

Overview

Verseon is a technology-based pharmaceutical company that employs its proprietary technology to design novel therapeutics for today’s challenging diseases. The Company has applied its platform to three drug programmes in the areas of anticoagulation, diabetic macular oedema, and oncology.

The pharmaceutical industry’s trillion dollar revenue stream is facing enormous challenges. Traditional techniques for finding drug candidates are based on trial and error and are prone to failure. Only one out of three drug discovery programmes deliver a single drug candidate to the clinic, and, after another six to seven years in clinical trials and regulatory review, only one out of fifteen programmes result in a newly approved drug. Consequently, the industry has seen a severe downward trend in the number of new drugs coming to market despite having increased new drug R&D spending to over $115 billion per year. There is a pressing need for a more reliable, effective and scalable drug discovery process.

The Company’s platform seeks to overcome this bottleneck by consistently designing novel drug candidates that the Directors believe are unlikely to be found using conventional methods. It can design multiple novel drug chemotypes per programme, so there are several choices available for human clinical trials. A drug programme with multiple candidates is more likely to succeed in clinical trials and result in a useful therapy.

Platform Summary

Verseon's proprietary platform is focused on accurate modelling of molecular interactions, development of sophisticated optimisation algorithms, and computer integration of synthetic and medicinal chemistry knowledge. The platform can consistently design novel drugs that the Directors believe are unlikely to be found using conventional methods and can be applied to virtually any target with known protein structure. It consists of a molecule creation engine, a molecule modelling engine, and efficient laboratory processes.

Verseon's molecule creation engine generates virtual drug-like, chemically-diverse, synthesisable molecules, in numbers that are far in excess of the distinct, synthesised compounds currently in the corporate collections of today’s pharmaceutical companies. This technology provides the Company’s medicinal chemists with a practically unlimited supply of novel potential drug candidates. The molecule creation engine also provides a synthetic recipe for every molecule, thus reducing uncertainty and cost when a molecule is ultimately selected for synthesis.

Verseon's molecule modelling engine evaluates the molecules designed by the Company’s molecule creation engine against a disease-causing protein of interest. This is accomplished with proprietary breakthroughs in physics-based molecular modelling of protein-drug interactions in an aqueous environment and sophisticated optimisation algorithms that can be deployed in parallel across a large dedicated, private computing cloud. High accuracy allows the Company to screen hundreds of millions of potential drug candidates for a given target protein without being overwhelmed by false positives and select the most promising subset for synthesis.

The synthesised candidates are then subjected to a battery of biochemical tests to measure relevant chemical and biological properties. Promising drug candidates are further characterised in the laboratory to assess pharmacokinetics, efficacy and safety. The candidates that are found to have the best properties in laboratory testing may be further optimized. The optimization process generates variations of these candidates using the molecule creation engine, selects the most promising using the molecule modelling engine, and sends them back to the laboratory for testing.

The Directors are not aware any competitor technology that rivals the Company’s molecule creation engine. Nor are they aware of any computational structure-based drug discovery technology with demonstrated performance that matches the Company’s molecular modelling engine. It is their view that the Company’s discovery platform represents a significant advancement over conventional methods whether computational or based on high-throughput screening.

Business Strategy

Verseon initially intends to out-license drug candidates at early stages of clinical development to pharmaceutical companies. As the business matures, it is expected that these out-licensing deals will be struck at progressively later stages of clinical development and, therefore, more value will be captured from the asset, although each potential licensing deal will be analysed on a case-by-case basis.

The Directors believe the reduced time and cost for drug discovery combined with the platform’s applicability to a wide range of therapeutic indications with strong market potential will enable Verseon to rapidly develop a large, diverse pipeline of valuable therapeutics. The Directors believe the Company’s drug candidates will be attractive to pharmaceutical licensees because the drug candidates are designed to be both highly potent and selective towards target proteins and, crucially, represent novel chemical matter that would not otherwise be accessible. The Directors also believe that Verseon’s ability to produce multiple, chemically-diverse drug candidates for each discovery programme will further increase the value proposition of out-licensing by increasing the likelihood of at least one drug candidate successfully passing through downstream clinical development. Licensing payments at preclinical or early stages of clinical development are typically in the form of upfront fees, milestone payments and royalties.

Verseon does not partner with or sell its technology platform to others. Instead, its technology platform is solely used to design novel drugs for therapeutic areas targeted by Verseon as per its pharmaceutical business model.

Current Drug Programmes

Experts agree that accurate computational modelling of protein-small molecule drug interactions is the key to efficient drug discovery. The Directors believe that Verseon has successfully demonstrated the capabilities of its proprietary drug discovery platform with its current portfolio of drug programmes which represent therapeutic areas with substantial market potential that are poorly served by existing drugs.

Anticoagulation

The Company’s most advanced programme is the development of novel oral anticoagulants for the treatment of cardiovascular disorders such as stroke prevention for atrial fibrillation patients, venous thromboembolism (including deep vein thrombosis and pulmonary embolism) and acute coronary syndrome. The total global anticoagulant market is forecast to surpass $24 billion by 2019. Verseon’s anticoagulants have demonstrated successful proof of concept in preclinical efficacy studies and also substantially reduced risk of major bleeding relative to existing anticoagulants.

Diabetic retinopathy/diabetic macular oedema

The Company’s second programme is aimed at degenerative diseases of the eye and in particular the development of novel therapeutics for the treatment of diabetic macular oedema (DME). The global market for DME in 2009 was approximately $3 billion and is expected to grow to $6.9 billion by 2017. Conventional therapies for DME require injection directly into the eye on a regular basis. Unlike existing therapies which treat downstream symptoms of DME via anti-angiogenesis (i.e. undesired blood vessel growth), the Company has taken a different approach and is focusing on the development of potent inhibitors of plasma kallikrein that could potentially be delivered via topical eye drops for the local ocular disruption of the kallikrein-kinin system, which is indicated in the DME disease pathway.

Oncology (solid tumours)

The Company’s third programme is a solid tumour oncology programme in the discovery stage for the development of novel angiogenesis inhibitors (AGIs). Currently, angiogenesis inhibitors are an important part of oncology treatments for a variety of cancers with a significant share of the oncology market. Conventional AGIs target vascular endothelial growth factor or other growth-related kinases in order to restrict blood flow into a solid tumour and reduce its supply of nutrients. Often these drugs are combined with other anti-cancer agents in a cancer treatment protocol. Verseon’s candidates represent a new class of AGIs that do not inhibit vascular endothelial growth factor or other growth-related kinases and also demonstrate low cytotoxicity.

Future Drug Programs

Verseon's drug discovery platform is applicable to virtually any clinical target with a known protein structure and, as such, provides the Company with great flexibility. Target selection is based on careful planning and involves several criteria including market opportunity, disease pathway validation and expected value proposition.

Use of Proceeds

The net proceeds of the Placing, amounting to approximately £60.7 million, will be used to fund the Company’s current portfolio of drug programmes and also to start new drug programmes to establish a diversified pipeline of high-value therapeutics across multiple disease areas. Other uses of the net proceeds will include expenditures for continued development of the Company’s drug discovery platform, expansion of the Company’s intellectual property portfolio and discovery infrastructure, business development, working capital and other general corporate purposes.
